The fourth volume of "Archeology of the Volga-Urals" summarizes the results of studies of archaeological materials reflecting the cultural and historical processes that took place in the Middle Volga and Urals during the era of the Great Migration of Peoples. This period went down in history as a time of large-scale migration processes that changed the ethnic map of Eurasia and caused radical transformations in the socio-economic and political way of life of its inhabitants. The publication presents a systematic presentation of the available archaeological data, grouped according to natural-geographical, chronological and historical-cultural principles. Each section of the volume contains the main positions of researchers on the interpretation of archaeological materials.
